Approval and Promulgation of Air Quality Implementation Plans; Delaware;
Section 110(a)(2) Infrastructure Requirements for the 1997 8-Hour Ozone
and the 1997 and 2006  Fine Particulate Matter National Ambient Air
Quality Standards

AGENCY:  Environmental Protection Agency (EPA).

ACTION:  Proposed rule.

SUMMARY:  EPA is proposing to approve submittals from the State of
Delaware pursuant to the Clean Air Act (CAA) sections 110(k)(2) and (3).

SUPPLEMENTARY INFORMATION:

I.  Background 

(μg/m3) based on a 3-year average of annual mean PM2.5 concentrations,
and a 24-hour standard of 65μg/m3 based on a 3-year average of the 98th
percentile of 24-hour concentrations.  EPA strengthened the 24-hour
PM2.5 NAAQS from 65μg/m3 to 35μg/m3 on October 17, 2006

(71 FR 61144).

Section 110(a) of the CAA requires States to submit State Implementation
Plans (SIPs) that provide for the implementation, maintenance, and
enforcement of new or revised NAAQS within three years following the
promulgation of such NAAQS.  In March of 2004, Earthjustice initiated a
lawsuit against EPA for failure to take action against States that had
not made SIP submissions to meet the requirements of sections 110(a)(1)
and (2) for the 1997 8-hour ozone and PM2.5 NAAQS, i.e., failure to make
a “finding of failure to submit the required SIP 110(a) SIP
elements.”  On March 10, 2005, EPA entered into a Consent Decree with
Earthjustice that obligated EPA to make official findings in accordance
with section 110(k)(1) of the CAA as to whether States have made
required complete SIP submissions, pursuant to sections 110(a)(1) and
(2), by December 15, 2007 for the 1997 8-hour ozone NAAQS, and by
October 5, 2008 for the 1997 PM2.5 NAAQS.  EPA made such findings for
the 1997 8-hour ozone NAAQS on March 27, 2008 (73 FR 16205) and on
October 22, 2008, (73 FR 62902) for the 1997 PM2.5 NAAQS.  These
completeness findings did not include findings relating to:  1) section
110(a)(2)(C) to the extent that such subsection refers to a permit
program as required by part D Title I of the CAA; 2) section
110(a)(2)(I); and 3) section 110(a)(2)(D)(i), which has been addressed
by a separate finding issued by EPA on April 25, 2005 (70 FR 21147). 
Therefore this action does not cover these specific elements.

II.  Summary of State Submittals

Delaware provided multiple submittals to satisfy section 110(a)(2)
requirements that are the subject of this proposed action for the 1997
8-hour ozone NAAQS, and the 1997 and 2006 PM2.5 NAAQS.  The submittals
shown in Table 1 addressed the infrastructure elements, or portions
thereof, identified in section 110(a)(2) that EPA is proposing to
approve.

EPA has analyzed the above identified submissions and is proposing to
make a determination that such submittals meet the requirements of
section 110(a)(2)(A), (B), (C), (D)(ii), (E), (F), (G), (H), (J), (K),
(L), and (M), or portions thereof.  A detailed summary of EPA’s review
and rationale for approving Delaware’s submittals may be found in the
Technical Support Document (TSD) for this action, which is available on
line at   HYPERLINK "http://www.regulations.gov"  www.regulations.gov ,
Docket number EPA-R03-OAR-2010-0158.

III.  Proposed Action

EPA is proposing to approve Delaware’s submittals that provide the
basic program elements specified in the CAA sections 110(a)(2)(A), (B),
(C), (D)(ii), (E), (F), (G), (H), (J), (K), (L), and (M), or portions
thereof, necessary to implement, maintain, and enforce the 1997 8-hour
ozone and PM2.5 NAAQS, and the 2006 PM2.5 NAAQS.  EPA is soliciting
public comments on the issues discussed in this document.  These
comments will be considered before taking final action.

IV.  Statutory and Executive Order Reviews   

Under the Clean Air Act, the Administrator is required to approve a SIP
submission that complies with the provisions of the Act and applicable
Federal regulations.  42 U.S.C. 7410(k); 40 CFR 52.02(a).  Thus, in
reviewing SIP submissions, EPA’s role is to approve state choices,
provided that they meet the criteria of the Clean Air Act.  Accordingly,
this action merely proposes to approve state law as meeting Federal
requirements and does not impose additional requirements beyond those
imposed by state law.  For that reason, this proposed action:

is not a "significant regulatory action” subject to review by the
Office of Management and Budget under Executive Order 12866 (58 FR
51735, October 4, 1993);  

does not impose an information collection burden under the provisions of
the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);

is certified as not having a significant economic impact on a
substantial number of small entities under the Regulatory Flexibility
Act (5 U.S.C. 601 et seq.);  

does not contain any unfunded mandate or significantly or uniquely
affect small governments, as described in the Unfunded Mandates Reform
Act of 1995 (Public Law 104-4);

does not have Federalism implications as specified in Executive Order
13132 (64 FR 43255, August 10, 1999);

is not an economically significant regulatory action based on health or
safety risks subject to Executive Order 13045 (62 FR 19885, April 23,
1997); 

is not a significant regulatory action subject to Executive Order 13211
(66 FR 28355, May 22, 2001); 

is not subject to requirements of Section 12(d) of the National
Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note)
because application of those requirements would be inconsistent with the
Clean Air Act; and 

does not provide EPA with the discretionary authority to address, as
appropriate, disproportionate human health or environmental effects,
using practicable and legally permissible methods, under Executive Order
12898 (59 FR 7629, February 16, 1994).

In addition, this proposed rule, pertaining to Delaware’s section
110(a)(2) infrastructure requirements for the 1997 8-hour ozone and
PM2.5 NAAQS, and the 2006 PM2.5 NAAQS does not have tribal implications
as specified by Executive Order 13175 (65 FR 67249, November 9, 2000),
because the SIP is not approved to apply in Indian country located in
the state, and EPA notes that it will not impose substantial direct
costs on tribal governments or preempt tribal law.
